extends DapSerializer

Given a DMR, return: 1. A byte array (byte[]) containing serialized data and DMR

Requirements: 1. repeatability: given the same DMR, return the same byte array

Notes: 1. Two options are provided for generating values: a. use of a random number generator with a fixed seed. b. use of a pre-defined sequence of values with repetition when the sequence is exhausted (not yet implemented).
